Using natural history information for zoo animal management: a case study with okapi (Okapia johnstoni)

Until recently, the impact that the presence of conspecifics may have on stereotypic behavior in naturally solitary species exhibited in zoological institutions has largely been ignored. This study examined the effect of adding a visual barrier between animal holding areas at the Brookfield Zoo on stereotypic head-rolling behaviour in an adult female okapi (Okapia johnstoni). Instantaneous sampling was used to document the proportion of time the female okapi spent head-rolling prior to and after visual barriers were constructed. Behavioural surveys were

Why and how should we use environmental enrichment to tackle stereotypic behavior?

This paper summarises recent findings on the causation of stereotypic behaviours and other abnormal repetitive behaviours (ARBs) in captive animals: primarily motivational frustration and/or brain dysfunction, with possible contributory roles also being played by habit-formation and ‘coping’ effects. We then review the extent to which ARBs occur in zoos and similar, estimating that at least 10 000 captive wild animals are affected worldwide. We argue for ‘zero tolerance’ of such ARBs, because stress and poor welfare raise ethical issues, while

Impact of a new exhibit on stereotypic behaviour in an elderly captive African elephant (Loxodonta africana)

Stereotypic behaviour in zoo elephants is considered an indicator of impaired welfare. The underlying causes are diverse and many aspects are still unexplored. Nevertheless, many zoological institutions make huge efforts to improve the well-being of their elephants. The construction of a new exhibit provides a chance to gain further evidence on the impact of such measures on elephant behaviour. We report a significant decrease in both the amount and frequency of swaying in an elderly African elephant (Loxodonta africana) after
